Status: RESOLVED DUPLICATE of bug 446693

(Core :: CSS Parsing and Computation, defect)

Description

[Jon Harald Søby]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1a1) Gecko/2008072310 Shiretoko/3.1a1

In Shiretoko, when you have a box with a shadow (-moz-box-shadow) that is positioned to the right edge of the screen, and the shadow falls outside the boundaries of the screen, a horizontal scroll bar appears. Try the following code in your favourite browser to see yourself:

<div style="position:absolute;top:20%;right:0;width:100px;-moz-border-shadow:#888 5px 5px 5px -2px;">Lorem ipsum</div>

Solution: border-shadow should not trigger the overflowing mechanism.

Reproducible: Always

Steps to Reproduce:
1. Add the code from the details to an empty .html and see for yourself.
Actual Results:  
A horizontal scrollbar appears; I guess (assumption) that a vertical scrollbar would appear if the box is position to the very bottom of the screen.

Expected Results:  
Not show a scrollbar.
